In the single-end push-pull circuit, for example, in Figure 23-8, a and C point are linked to be in low potential. But the earth point is not limited, any points on the coil a-b associating with the same potential point on the coil o-d can be used as earth point. In Figure 23-12, to connect the two mid-points of a-b, o-d to the earth, this is the basic form of Rick McIntosh amplifier circuit.
The two primary coils of the output transformer in circuit are directly related to the two primary coils of single-ended push-pull circuit, the everywhere's potential along the two potential coils is the same, so the primary coil is not influenced by electrostatic distributed capacitance, although they are two-lane around. This is one feature of Rick McIntosh amplifier circuit.

The basic form of circuit diagram
Figure 19-1 shows the most representative form of two-stage negative feedback amplifier circuit. In this circuit, the feedback voltage of the R1 connects to the input signal in series, so the circuit is in series input type. In the figure, the plate load impedances of R1 and V1 are series connected, on the other hand, the plate load impedances of R1 and V1 are parallel connected to R2. So the circuit is a current feedback circuit for V1, and a voltage feedback circuit for V2. In fact, the current feedback component of V1 is much smaller than the total voltage feedback component of V2, so the whole circuit is used as a voltage feedback circuit.
